Abstract

A method, system, and connector interface for transferring status information between a media player and an accessory. The method includes determining, by the accessory, when a button event occurs; and transmitting, by the accessory, at least one button status command to the media player, where the one or more button status commands comprise a context-specific button status command and at least one command associated with a particular media type. According to the method and system disclosed herein, the media player and accessory may utilize a plurality of commands in a variety of environments such as within a connector interface system environment to facilitate the transfer of status information.

Claims

1. A method for operating a media player, the method comprising:

receiving, by the media player, a button status command from an accessory communicatively coupled to the media player, the button status command being a command from a group of supported commands consisting of a context-specific button status command to control particular actions of the media player and one or more media-type-specific button status commands to control playback of one or more different media types,

determining, by the media player, an action to be performed in response to the button status command, wherein the determination is based at least in part on whether the button status command is the context-specific button status command or one of the one or more media-type-specific button status commands; and

performing the determined action.

2. The method of claim 1 wherein in the event that the context-specific button status command is received, the determining is performed in a context associated with an active application executing on the media player.

3. The method of claim 2 wherein in the event that the media-type-specific button status command is received, the determining is performed in a context associated with an application on the media player that plays media of the specific type.

4. The method of claim 1 further comprising transmitting to the accessory, by the media player, an acknowledgement status command in response to the button status command.

5. The method of claim 1 wherein the one or more media-type-specific button status commands include:

an image button status command associated with a playback application for still images;

a video button status command associated with a playback application for video; and

an audio button status command associated with a playback application for audio.

6. The method of claim 4 wherein the button status commands include support a plurality of buttons including at least:

play/pause;

volume up;

volume down;

next track;

previous track;

next image; and

previous image.

7. The method of claim 4 wherein the button status commands include support a plurality of context-specific buttons including at least:

play/pause;

volume up;

volume down;

next track;

previous track;

next image;

previous image;

next album;

previous album;

up arrow; and

down arrow.

8. The method of claim 1 wherein receipt of the button status command is preceded by an authentication of the accessory.

9. A media player comprising:

control logic configured to execute a plurality of applications for playing back stored media, each application associated with a different media type;

an interface configured to communicably couple the media player to an accessory; and

command logic coupled to the control logic and the interface, the command logic being configured to receive from the accessory a button status command from a group of supported commands consisting of a context-specific button status command associated with particular functions of the media player and one or more media-type-specific button status commands, each media-type-specific button status command being associated with a playback application for a different media type,

wherein the control logic is further configured to determine an action to be performed in response to the button status command, wherein the determination is based at least in part on whether the button status command is the context-specific button status command or one of the one or more media-type-specific button status commands, and to perform the determined action.

10. The media player of claim 9 wherein the control logic is further configured to notify the accessory when the state of the media player changes.

11. The media player of claim 10 wherein the states of the media player include at least:

on, off, sleep and hibernate.

12. The media player of claim 10 wherein the control logic is further configured to transmit to the accessory an acknowledgement status command in response to the button status command.

13. The media player of claim 10 wherein the one or more media-type-specific button status commands include:

an image button status command associated with a playback application for still images;

a video button status command associated with a playback application for video; and

an audio button status command associated with a playback application for audio.

14. A method for transferring status information between a media player and an accessory communicatively coupled to the media player, the method comprising:

determining, by the accessory, when a button event occurs; and

transmitting, by the accessory, at least one button status command to the media player, the button status command being a command from a group of supported commands consisting of a context-specific button status command to control particular actions of the media player and one or more media-type-specific button status commands to control playback of one or more different media types.

15. The method of claim 14 further comprising receiving from the media player, an acknowledgement status command in response to the button status command.

16. The method of claim 14 wherein the one or more media-type-specific button status commands include:

an image button status command associated with a playback application for still images;

a video button status command associated with a playback application for video; and

an audio button status command associated with a playback application for audio.

17. The method of claim 14 wherein the button status commands support a plurality of buttons including at least:

play/pause;

volume up;

volume down;

next track;

previous track;

next image; and

previous image.

18. The method of claim 14 wherein the button status commands support a plurality of context-specific buttons including at least:

play/pause;

volume up;

volume down;

next track;

previous track;

next image;

previous image;

next album;

previous album;

up arrow; and

down arrow.

19. The method of claim 14 wherein transmitting, by the accessory, at least one button status command to the media player is preceded by transmitting, by the accessory, a response to an authentication query received from the media player.

20. An accessory comprising:

a device for transferring data;

an interface coupled to the device; and

a command set in communication with the interface, wherein the command set enables the media player and an accessory to transfer status information therebetween, the command set comprising;

at least one command for determining, by the accessory, when a button event occurs; and

a plurality of commands for transmitting, by the accessory, to the media player at least one button status command from a group of supported commands consisting of a context-specific button status command associated with particular functions of the media player and one or more media-type-specific button status commands, each media-type-specific button status command being associated with a playback application for a different media type.

21. The accessory of claim 20 further comprising receiving from the media player, an acknowledgement status command in response to the button status command.

22. The accessory of claim 20 wherein the one or more media-type-specific button status commands include:

an image button status command associated with a playback application for still images;

a video button status command associated with a playback application for video; and

an audio button status command associated with a playback application for audio.

23. The accessory of claim 20 wherein the button status commands include support a plurality of buttons including at least:

play/pause;

volume up;

volume down;

next track;
